|

| 5 | openssl-nseq,
|
|---|
| 6 | nseq - create or examine a Netscape certificate sequence
|

| 8 | =head1 SYNOPSIS
|
|---|
| 9 |
|
|---|
| 10 | B<openssl> B<nseq>
|
|---|
| 11 | [B<-help>]
|
|---|
| 12 | [B<-in filename>]
|
|---|
| 13 | [B<-out filename>]
|
|---|
| 14 | [B<-toseq>]
|
|---|
| 15 |
|
|---|
| 16 | =head1 DESCRIPTION
|
|---|
| 17 |
|
|---|
| 18 | The B<nseq> command takes a file containing a Netscape certificate
|
|---|
| 19 | sequence and prints out the certificates contained in it or takes a
|
|---|
| 20 | file of certificates and converts it into a Netscape certificate
|
|---|
| 21 | sequence.

| 23 | =head1 OPTIONS
|
|---|
| 24 |
|
|---|
| 25 | =over 4
|
|---|
| 26 |
|
|---|
| 27 | =item B<-help>
|
|---|
| 28 |
|
|---|
| 29 | Print out a usage message.
|
|---|
| 30 |
|
|---|
| 31 | =item B<-in filename>
|
|---|
| 32 |
|
|---|
| 33 | This specifies the input filename to read or standard input if this
|
|---|
| 34 | option is not specified.
|
|---|
| 35 |
|
|---|
| 36 | =item B<-out filename>
|
|---|
| 37 |
|
|---|
| 38 | Specifies the output filename or standard output by default.
|
|---|
| 39 |
|
|---|
| 40 | =item B<-toseq>
|
|---|
| 41 |
|
|---|
| 42 | Normally a Netscape certificate sequence will be input and the output
|
|---|
| 43 | is the certificates contained in it. With the B<-toseq> option the
|
|---|
| 44 | situation is reversed: a Netscape certificate sequence is created from
|
|---|
| 45 | a file of certificates.

|
|---|
| 50 |
|
|---|
| 51 | Output the certificates in a Netscape certificate sequence
|
|---|
| 52 |
|
|---|
| 53 | openssl nseq -in nseq.pem -out certs.pem
|
|---|
| 54 |
|
|---|
| 55 | Create a Netscape certificate sequence
|
|---|
| 56 |
|
|---|
| 57 | openssl nseq -in certs.pem -toseq -out nseq.pem
|
|---|
| 58 |
|
|---|
| 59 | =head1 NOTES
|
|---|
| 60 |
|
|---|
| 61 | The B<PEM> encoded form uses the same headers and footers as a certificate:
|
|---|
| 62 |
|
|---|
| 63 | -----BEGIN CERTIFICATE-----
|
|---|
| 64 | -----END CERTIFICATE-----
|
|---|
| 65 |
|
|---|
| 66 | A Netscape certificate sequence is a Netscape specific format that can be sent
|
|---|
| 67 | to browsers as an alternative to the standard PKCS#7 format when several
|
|---|
| 68 | certificates are sent to the browser: for example during certificate enrollment.
|
|---|
| 69 | It is used by Netscape certificate server for example.
|
|---|
| 70 |
|
|---|
| 71 | =head1 BUGS
|
|---|
| 72 |
|
|---|
| 73 | This program needs a few more options: like allowing DER or PEM input and
|
|---|
| 74 | output files and allowing multiple certificate files to be used.
